Application filed November 25,1913. Serial No. 802,870.

To all whom; it may concern Be it known that l, Hnnnnn'r H. Hnwrrr, a citizen of the United States, and a resident'of Buffalo, county of Erie and E'ltate of New York, have invented certain new and useful Improvements in GanTrucks of which the following is a full, clear, anc ex- I act description.

T lie present invention relates to car trucks and seeks to provide means for mounting the journal box in amanner permitting the independent axial. movement of the wheel axles relatively to the truck to thereby relieve the truck and car body from shocks and strains when passing around curves or other irregularities of the track.

More particularly, the invention relates to car trucks in which the construction permits the rocking movement of the truck side frames and wheel axles, so that all of the wheels of the truck may rest solidly on the track, in spite of irregularities thereof and without straining or distorting the parts of the truck, and the invention seeks to pro-- vide simple and effective means for mounting the journal boxes which will permit both rocking and axial movements of the wheel axles in transverse vertical planes. A

further object of the invention is to provide this desired flexibility and at the same time provide strong, simple construction in be readily assembled orytaken apart for repairs and the like.

The-invention consists in the features of construction hereinafter set forth, illustrated in the preferred form in the accompanying drawings and more particularly pointed out in the appended claims.

in the drawings, Figure 1 is a plan view of a half portion of the truck with parts of one of the, side frames shown in horizontal section. Fig. 2 is a view partly in elevation and partly in vertical section through one end of one of the side frames and through.

one of the journal boxes. Fig. 3 is an end view of the improved truck with one end'of one of the side frames shown in vertical sec tion. Fig. 1-, is an isometric view of one end of the side frames with the journal box mounted thereon.

The general construction of the truck is preferably similar to tliat set forth in prior Letters Patent of the United States issued to me heptemher 9, 1913, Nos, 1,072,722 and 1,012,725. As set forth in these patents,

11ions 18 which fit within each side frame is preferably diamond shape in outline and comprises an enlarged central portion 10 and opposite pairs of inclined, converging side arms 11 which extend from the upper and lower parts'of the central portion and which are connected at their outer ends by the vertical, transverse flanges 12. .The parts of the side frame are preferably formed of a single casting comprising a vertical central web having wide, outer, marginal flanges 13 and narrow, inner, marginal flanges 14. The central portion of the side frame is provided with a transverse circular opening having a cylindrical edge flange which, like the flanges 13 and 14, project in opposite directions from the central web of the side frame and which forms an enlarged,transverse, cylindrical bearing 15. This cylindrical bearing is slightly wider than the edge flanges 1 1 and is connected thereto by diagonal bracing flanges 16.

The transverse connecting means between the side frames in the form shown, com prises a truck transom 17 which is provided at its ends with cylindrical journals or trunthe bearings 15 of the side frame. The side frame is provided with enlarged the bearing 15, and which are provided with pockets for receiving keys 20, the inner ends of which extend within slots 21 in the sides of the hollow trunnions or journals 18. The keys are removably held in position by bolts 20 and are arranged to removably secure the side frame upon the end journals of the transverse connecting means of the truck in a manner permitting the limited, independent rocking movement of each of the truck side frames in a longltud nal, vertical plane.

box is preferably formed of an integral'body of metal and is provided with a bearing or brass S0 for engaging the journal Q8 of the car axle,

bosses 19 on opposite sides of Each box is arranged Within an opening .in-theend of the side frame, and which opening is preferably formed by upper and ."i'lower integral extensions 31 and 32 which '5- project laterally on theend flange 12' of the "-side frameabove and below the ournal box.

The construction provided for mountin the journal box'is strong, but the journa boxes and Wheel axles can move axially independently .of the side frames, so that lateral shocks and thrusts imparted to the Wheels in roundin I ,swi ches and the l' e are not imparted to '6 the truck or to thecar body carried therea by. -l.'t should be noted that the swinging hangers are so arranged thatif one of the Wheel axles shifts axially relatively to the side frames, the latter are interposed between the sideframes and jour-. nalbojXes-to permit the transye rse'or am'al he journal. boxes and the mgingghan g'eriinks 33 fo each or,

The inner hanger link is first placed in position by passing its lower end iajge semi-circular seats and 32 to thereby removably rcurves, passing. over I lifted slightly so he that the weight of the truck and of the our t body thereon tends to restore and hold the hangers in normal vertical position and thus tends to center the journal boxes relatively to the side frames.

The construction is also journal boxes can oscillate or verse vertical planes and, inasmuch as the side frames are free to rock independently on the ends of the transverse connecting member of the truck, the wheels will, at all times, rest solidly on the track and are free to rise and fall in passing over irregularities of the rails Without. transmitting the shocks and strains due to such irregularities to the transverse connecting member of the or to the car body carried thereby. The improved construction will therefore, decrease the Wear and the strain upon the parts of'the truck and car body and will reduce the wear of the bra-sees and of the wheel flanges and rails.

The parts for flexibly journal box such that the rock in transconnecting the side may be readily asover the lower end extension 82. The jonr nal box is then inserted and its inner trunnion placed within the upper end of the inner hangerlink. The outer hanger link is then placed in position with its upper and 1 1 extending around the outer trunnion. of the box and its lower endaround the lower extension. The parts are then held 111 pc? sltion by means of the upright 36 and the bolt readily in horizontal direction lengthwise of the side frame and Without elevating the truck. The extensions 31 and o preferably -11 for receiving bolts by an ordinary Master Car Builders 'jdurnal box may be rigidly secured in. position if desired or necessary in case of accidentgj While the improved manner of mounting the journal boxes is advantageous in atrucir in which the side frames are srviteled for independent rocking :rnovemei t 'itis obvito advantage" in car trucks of other ume'rous changes may be made in the details set forth Without departure from the essentials 09f the invention as,defined in the claims. p
